I have always found this story of the disrobing of Draupadī, the wife of the godly King Yudhiṣṭhira, to be and example of how Krsna always protects his pure devotees. This incident contributes greatly to the Great Battle of Kurukṣetra, which almost completely annihilated the Kuru’s. And is a very good example of Spiritual Blindness. The following is a few select verses from the Srimad-Bhagavatam and Bhagavad-gita As It Is.

Dhṛtarāṣṭra was blind from birth, but his blindness in committing impious activities to support his dishonest sons was a greater blindness than his physical lack of eyesight. The physical lack of sight does not bar one from spiritual progress. But when one is blind spiritually, even though physically fit, that blindness is dangerously detrimental to the progressive path of human life. (SB 3.1.7 purport)

Dhṛtarāṣṭra was blind from birth. Unfortunately, he was also bereft of spiritual vision. He knew very well that his sons were equally blind in the matter of religion, and he was sure that they could never reach an understanding with the Pāṇḍavas, who were all pious since birth. (Bg 1.2 purport)
